I suspect this may be a browser/platform issue.  I've recently run some
tests and below are the most interesting results (mime types):

IE 6 on PC:
something.jpg   ->              image/pjpeg
something.tif (pc format) ->    application/octet-stream
something.tif (mac format) ->   image/tiff

IE 5 on Mac:
something.bmp ->                application/octet-stream
something.jpg ->                image/jpeg


NS 4.7 on Mac:
something.bmp   ->              image/x-MS-bmp

Opera 7 on PC:
something.bmp   ->              image/x-windows-bmp

I suspect if you want to validate jpgs, use image/jpeg and image/pjpeg or
validate by examining the extention (ie ".jpg").  I don't know how safe the
latter is.

HTH,

> Hi All,

> $ReturnSaying = "!! The file is not a JPEG picture. Please try again";
> include("photo_error.php");
> exit;
>
> Anyway, this system has been tested and tested again on multiple
